| Abstract: | This paper presents a column-extractions method in which XAD-4 resin impregnated with 7-Dodecenyl-8-Quino lion (DDQ) was selected packing, and studies the suitable working conditions,such as the extraction and enrichment of the trace elements including Maganese, Nickel, Copper, Cadmium, Bismuth and Gallium in seawater. This method has advantages, with high efficiency enriching those trace elements, without contamination, but with high determinative sensitivy as well as high automation, The relative standard deviation of this mothod in over the range of 1.34~4.00% and it is suitable for the determinations of a large banch of samples such as seawater, etc. |
